etching new fiberglass

[Tor]

Does anyone know the acid/solvent used for etching new fiberglass, to remove the surface wax?

Are you asking about removing all the mold release from the
fiberglass? If so Interlux 202 or MEK.

Usually a combination of solvents, though acetone is effective.
Try this link.

Oops, sorry, 202 is the right stuff, not 2333n. Got my jugs mixed up.

If its your bottom you’re cleaning, here’s a link to the interlux instructions.

Thank you all for those suggestions. Was hoping for something generic and likely to be lying around already,
like MEK or acetone, since I only need to etch the few square feet of my new windvane rudder & trim tab below
the waterline. I’ve already sanded the surfaces thoroughly with 60-grit wet and would be surprised if any
surface wax remains, but I want to be sure.

Thanks again.

yes, MEK or acetone will work…just don’t breathe any vapors…both are carcinogen suspects.

Thanks, Joseph. I’ll be careful with the vapors. Gave that stuff up in favor of beer years ago.

Hi Tor,
 
I'll weigh in on the subject – acetone will do the job.  You're just removing wax, grease, or release agent and it does the trick.  And you're more likely to have it hanging about.  MEK works, too, but I avoid using it because of it's ability to be absorbed through the skin. 
 
Good luck with the job!
